SERVER-61976 Retry failed shard version refreshes on step up

On step-up, shards will clear the filtering metadata and schedule a
shard version refresh for the source collection and the temporary
resharding collection. It is possible for the shard version refresh
triggered through onShardVersionMismatch() to error and not complete the
shard version refresh. This can leave a recipient shard waiting to learn
all donor shards are prepared to donate or can leave a donor shard
waiting to learn all recipient shards have finished cloning.

Therefore, shards now will retry on errors until the refresh
successfully completes.
